https://angusreid.org/omicron-incidence-restrictions/ - scroll down to "Part Four: What now? Majority want restrictions to end"; 54% of Canadians want the mandates to end. OTOH, this poll https://abacusdata.ca/ottawa-survey-freedom-convoy/ suggests that about 22% of Canadians support the convoy and 67% don't.
It's all down to how a poll accurately frames a question: Do people like restrictions? No, nobody likes restrictions. Do people like restrictions that save lives? Still don't 'like' them but believe sacrifice is necessary for the greater good. Do I support people's right to protest? Yes, but... You can't honk all night Block major infrastructure for days Desecrate war monuments Flood 911 with fake calls Etc.
I suspect how much people support "people's right to protest" is directly proportional to how much they support The Cause. If they don't support The Cause, they want protesters to be as out of the way as possible (ie. "free speech zones"). If they do support The Cause, anything up to and including violence/vandalism is justified, because a few causalities would be canceled out by all the positive effects that The Cause would bring.
